Application filed February 5, 1921. Serial No. 442,794.

T 0 all to 710m it may concern.

Be it known that 1, CHARLES H. WAKE, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Tooth Cleaning and Polishing Bur, of which the following is a specification.

This invention relates to a dental bur or bit for use in cleaning and polishing teeth, one of its objects being to provide a device of this character which can be connected readily to various types of dental engines and which is so constituted as to quickly and thoroughly clean the surfaces to which it is applied, it being possible to provide said drill or bur in any shape desired or to shape it to meet any desired condition.

A further object is to provide a device of this character which is formed of soft rubber having minute pores and which has combined therewith a polishing agent in a powdered form.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that within the scope of what is claimed, changes in the precise embodiment of the invention shown may be made without departing from the spirit of the invention.

In the accompanying drawings the pre ferred forms of the invention have been shown.

In said drawings- Figure 1 is a side elevation of a tubular device connected to a porte polisher such as used in connection with dental engines.

Figure 2 is an end elevation of the article shown in Figure 1.

Figure 8 is a side elevation of a solid "form of the article connected to the chuck of a dental engine, the said article having a beveled end.

Figure 4 is an end elevation of the article.

Figure 5 is a side elevation of one of the polishing devices having its end provided with a taper and double bevel.

Figure 6 is an end elevation thereof.

Figure 7 is a side elevation of another form of the polishing devices with both ends beveled.

Figure 8 is an end elevation thereof.

Referring to the dra g it will be no ed lar form of the device will be found of considerable utility under certain conditions and can be used to advantage where a solid polishing device cannot be employed. If preferred, however, the polishing device can be in the form of a solid stem 2, cylindrical if desired, and one end of which can be beveled as indicated at 3. here a solid stem is used the same is held within the ordinary chuck B of a dental engine. Under some conditions the beveled end of the stem can have its sides cut away as indicated at i in Figures 5 and 6. thus to bring the articles to a point as shown at 5. Also, instead of. beveling only one end of the stem, as shown in Figure 3, both ends thereof can be beveled as indicated at 6 in Figure 7.

The article constituting the present invention is preferably formed of rubber or a rubber substitute having combined therewith a finely comminuted material such as powdered pumice or the like, the said rubber base being formed with minute pores so that when the article is applied to the surface being treated the abrading particles can be brought properly into contact with the surface and quickly clean and polish it.

Obviously while certain shapes and sizes have been illustrated it is to be understood that the articles can be made of various other shapes and proportions. The invention resides primarily in the use of a base of rubber or rubber substitute having minute pores and having thoroughly commingled or mixed therewith a finely comminuted abrasive. Another feature of importance is in the use of a tubular cleaning and polishing member such as shown in Figures 1 and 2.

What is claimed is 1. An article of the class described comprising an elongated member tubular throughout its length and having a beveled end, the other end of the member constituting means for receiving a porte polisher, said member comprising coarse flexible rubber mixed throughout the thickness and length of its walls with a finely comminuted abrasive.

2. The combination with a porte polisher, of a flexi le rubb r relishing d i e tubular throughout its length and mounted on and as my own, I have hereto afiixed my signagripping one end of the pof 'te olisher, said ture in the presence of two Witnesses. device includin a base 0 soft rubber or r the like having minute pores therein and CHARLES WARE 5 mixed throughout its extent with a finely Witnesses:

comminuted abrasive substance. CATHERINE VAKE,

In testimony that I claim the foregoing MINNIE E. RoBsoN.
